As someone who lives in Russia, I can confirm that this "troll farm" actually exists. There are many evidences of their work here. This "troll farm" has a lot of employees, and it uses a huge amount of fake accounts to make comments in social media. Usually those fake accounts are spamming with dislikes and comments under Russian opposition's posts and anything that criticizes our government. They are trying to shape society's opinion on important topics by making it look like there is a particular narrative supported by the majority of people. I am not sure what they were doing during US election, but i am well aware about things that they do here in Russia.
PS: Do not believe anything you read on the internet, base your opinion on facts and real evidences.
